Ryan,
I have had an intermittent in my M100 for the last 10 years that is
similar to this. From memory, I found an issue with the -5V supply that
was causing the issue.
When it is faulty, open the case, and check the supply voltages.
Do you have the M100 Service manual?

I have confirmed it reads 4.06 volts after approx 24 hours after being
unplugged from roughly a 24 hour charge. What is weird, is after the
suggestion of reseating socketed connections, (I only found one IC with a
socket) and after reseating it, it booted up fine every time for ~10 times, now
back to the issue. Of note, when the issue reappeared after working those 10
times, when continued off-on finally succeeded once, I noticed the date time
was reset. During those 10 successful startups however the clock was not reset,
as expected.

might be worthwhile to just check the voltage on it... make sure the
battery is able to hold a charge at 3.6V and is not a bad battery.
sounds like you keep getting ram corruption.

Good call on the reseat, I will do that as a good measure.
Yes, I've replaced the nicad and have charged overnight, though I haven't
done anymore troubleshooting to confirm operation of the nicad circuit.

In your first post you said you replaced the internal battery, I assume that
was the soldered in place ni-cad. The next step that I would do is to
disconnect every connector be sure the contacts are clean and re insert it.
This might be all that's needed. This should include any socketed chip as
well.

Lee, though this trick certainly did work, it seems this needs to be
repeated each time. Once turned off, then back to square one. Something
else odd, is that the trick appears to work only ~50% of the time, whereas
just turning off and on, will not result in anything more than the solid
pixels.

The m100 had an internal nicd battery. Normally units I get off eBay have
to sit plugged into the wall wart overnight before they function properly.
It could also be that your nicd is shot and needs to be replaced. You
could check the voltage across it after letting it charge.
